TO A LL WHOM 1T MAY CONCERN:

Be it known that I, MARX THODE, of Mattoo'n, in 'the county of Coles,and State of Illinois, have invented new and Vuseful Improvements inSubterranean Walls; and I do hereby declare that the'following is afull, clear,rand exact description thereof, which Willenable-othersskilled in the art to make and-use the s.a.uie,rofer ence being had totheaecompanying drawings forming part of this specification.

Figure l is a vertical section-'cfa cylinder, constructed according tomy improvements.

Figure 2 is u. horizontal section ofthe same.

Similar letters o-f'reference indicate corresponding parts.

This i'nvention'consists' in forming the wells of cisterns, cellars, orother subterranean structures in two parts, or double, with aninterlin-ing of pitch, asplmltum, or other equivalent resinoussubstances, by which means water or dampness is excluded.

The walls and floor are of' briclc or cement,^and th'e manner ofconstruction is asfollovws: i

A iioor, b, is rst laid upon the wooden sleepers d, 'as shown. vThisiioorV may be of wood, or it may be of plank, laid first, and coveredwith brick.

The edges are bounded by a tier of brick or afwooden batteu, and meltedpitch,lasphnltum, or other equivalent thereof, is poured upon the floor.l

The exterior Wall, e, and the inner wall, g, are then built u-ptogether,` being filled with the pitch or asphaltuxn as the walls rise i5 The exterior wall rests on its foundation outside'of the iioor b, butthe inner wall rises fromtho said floor, as shown. Y

A bottom, d, of brick or cement is afterwards laid over thepitch, toprotectit from injury or wear.

These improvernentsQwhen employed in the construction of cellars, willcause the same to oe water-tight, and totally free from dampness in allseasons.

When Icisterns are sorconstructed they will not leak n or permit thewater Within them to become impure from the percolation of exteriordrainage. i' i I claim as new, and desire to secure by Letters Patent-In' the formation of subterranean structures, the employment of doublewalls e g, with the space between them filled withvpitch, m, orosph'altum or other impervious material, to be melted and poured thereinas the walls are built up; ande. bottom, formed bythe layers el, with alayer of pitch-or asphaltum m between them, all constructed and arrangedas described for the purpose specified.

MARX, irHoDE.`
